Aunque en algunas infraestructuras pueden construirse pasos espec\u00edficos para la fauna, normalmente se adaptan drenajes y pasos inferiores para que puedan ser utilizados tambi\u00e9n por la fauna. En Catalunya (NE de Espa\u00f1a) se llev\u00f3 a cabo un estudio con el objetivo de identificar las caracter\u00edsticas ambientales y estructurales que tienen una influencia significativa en el paso de fauna. 56 estructuras transversales (potencialmente utilitzables como pasos de fauna) se controlaron para determinar si eran utilizadas o no por los animales; 39 eran de secci\u00f3n circular (de 1 a 3 m de di\u00e1metro) y 17 eran de secci\u00f3n rectangular (de 4 a 12 m de ancho). La informaci\u00f3n se obtuvo registrando huellas sobre un sustrato de polvo de m\u00e1rmol y utilizando camaras de filmaci\u00f3n y fotogr\u00e1ficas activadas por un haz de infrarrojos. Las preferencias de los distintos grupos taxon\u00f3micos fueron analizadas para facilitar recomendaciones aplicables al acondicionamiento de estructuras transversales como pasos de fauna. Las caracter\u00edsticas que facilitan el paso de fauna mostraron notables diferencias para cada uno de los grupos analizados. Los peque\u00f1os mam\u00edferos y los carn\u00edvorsos fueron los grupos que se detectaron con mayor frecuencia. Los ungulados presentes en el \u00e1rea (corzo y jabal\u00ed) no utilizaron ninguna de las estructuras durante el per\u00edodo de muestreo. Una prospecci\u00f3n espec\u00edfica que se llev\u00f3 a cabo en los pasos inferiores una vez al mes durante un a\u00f1o, estableci\u00f3 que el jabal\u00ed utilizaba (aunque s\u00f3lo ocasionalmente) las estructuras de m\u00e1s de 7 m de anchura.", "es": "The permeabilisation of linear infrastructures is essential to mitigate the fragmentation that new infrastructures cause on wildlife populations.
